摘要
利用空间有限元法,用通用有限元软件ANSYS对体外预应力箱梁的关键部位锚固块进行了静力分析、主应力迹线分析,得出了锚固块的应力变化规律,继而进行拉压杆模型法配筋,从而保证体外预应力锚固块的合理配筋,推广空间拉压杆模型法的应用。
Based on the space finite element method, researchers get static stress analysis and principle stress trajectories analysis on the key parts anchor block of external prestressed box beam according to the common finite element software ANSYS, get the stress change law of anchor block, further gets reinforcement based on the strut-and-tie model method, thus ensuring the reasonable reinforcement of the external prestressed anchor block, and promoting the application of the space strut-and-tie model method.
